MACHINE FOR MAKING CORDAGE.

SPECIFICATION forming part of Letters Patent No. 227,940, dated May 25, 18180. i

' Application filed Juno 18, 1879.

To all whom it may concern:

Beit known that I, GILMAN K. WrNonEs TER, of Providence, in the county of Providence and State of Rhode Island, have invented certain Improvements in Machines for MakingOordage, in which the strands are combined by an interlocking twist, of which the following is a full, clear, and exact descrip tion, reference being had to the accom panyin g ro drawings, making part of this specification, in

which- Figure 1 is an elevation of one .side of my improved machine. Fig. 2 is a plan of the same, the take-off roll, with its connecting I 5 mechanism and supporting-ba1,beingremoved. Fig. 3 is a plan of the table or to'p of the machine, the spools and their carriers being removed. Fig.4 is a vertical section through the center of the machine. Fig. 5 is a horizontal section on the line a' a: of Fig. 4. Fig.

6 is a sectional detail. Fig. 7 is a central vertical section through one of the spools and its carrier. Fig. Sis a horizontal section on the lineyyofFig. 7.

My invention relates to that class of machines form aking cordage in which the strands are combined by an interlocking twist, and has for its object to simplify the construction of these machines, so as to render them more 3o durable and less expensive to build and keep in repair, and also to enable them to be run with greater speed than heretofore, thus increasing the production of the cordage made thereby.

To this end my invention consists in sundry details of construction, as hereinafter fully described and claimed.

To enable others skilled in the art to understand and use my invention, I will proceed to 4o describe the manner in which I have carried it out.

In the said drawings, A represents the bed of the machine,which is supported on legs a, and is provided on its under side with lugs b, 5 in which are formed bearings for the horizontal driving-shaft B, at one end of which is the driving-pulley C and a clutch mechanism, D, and at the opposite end a bevel-pinion, d, `ch engages with and drives a large horil bevel-gear, E, to which is keyed a vertical shaft, c, which passes up through the center of the machine, and has securely fixed to it a plate or platform, H, from which rise posts or studs j", to the upper ends of which is secured a circular table or disk, G, which isV thus caused to revolve with the platform H when the latter is turned by the shaft c.

Between the bed A and platform H is placed a large stationary gear-wheel, I, which is held immovably in place by means of screw-bolts 6o g, and with this wheel I engagesaslnall gear, K, secured to the lower end of a short vertical shaft, h, having its bearing vi n the platform H, this shaft h having also secured to it, between the table G and the platform H, another small gear, L, lwhich engages with a gear, M, of a series fof six gears, M N O P Q R, which revolve around sleeves c' on vertical bolts k, ar ranged at equal distances apart around the periphery of the platform H, to which they are secured by nuts I.

The gear M, which is driven by the gear L, engages with and rotates a central gear, S, which revolves on a sleeve, m, surrounding the vertical shaft c, and this gear S engages with and drives in the saine direction all the rest ofthe series of gears, each of the gears M N O P Q, R being provided with a forked plate, T, ofthe form seen in Fig. 5, each plate having four pairs of prongs or horns, n, pro- 8o jecting from it, forming four notches or bifurcations, p, which are arranged at equal distances apart.

The central gear, S, is also provided with a forked plate, U, of similar form to those T, but having six pairs of prongs or horns, q, forming six notches or bifurcations, r, these horns q being located in a horizontal plane just below that of the horns n, which overlap the horns q.

V are the spools or bobbins (ten in number) 9o upon which the threads or strands sare wound, these spools revolving upon vertical spindles rising from their carriers W, each of which consists of an upper plate or portion, l2, and a lower plate, 13, fitting the former upon the upper surface and the latter against the undersurface of the table Gr, these two plates l2 13 being connected by an elongated elliptical web or portion, c, pointed at both extremities, (see Fig. 8,) which lits within the grooves -or roo raceways of the table G, pins or projections 14 on the under side of the bottom plates, 13, of the carriers W extending down between the horns ofthe plates T by which the carriers W,with their spools, are actuated and caused to travel through the raceways. These raceways consist of a series of straight slots, t, arranged around the center l5, forming a hexagonal track, and a series of circular slots, u, foi-min g circular tracks, which are connected with or intersect the hexagonal track, each votl the straight slots t being tangent to the two circular slots u adjacent thereto, as seen in Fig. 3, the table G consisting of the main portion 15, a hexagonal portion, 17, secured on the top ot' the sleeve m by a nut, 18, and a series ot' nearly circular portions, 19, secured on the tops of the sleeves by means of the bolts 7c.

As the table G is rotated the spool-carriers W, with their spools, are each caused to travel, withoutinterruption ot' motion, tirst around one ofthe circular slots u in the direction ot' the arrow until it arrives at the intersection ofthe contiguous straight slot t therewith, when its pin 14 enters one of the bifurcationsv r ot' the plate U, which is at that' time in the proper position to receive it. The carrier WV is now moved by the plate U through the straight slot t to the next circular slot a, when the pin 14E enters 011e ot' the bifurcations p of the next plate, T, by which it is carried around the next circular slot a to the next straight slot t, and so on entirely around the table G, each spool passingl over precisely the same track as its predecessors-viz., around a common center in the raceways t, and successively aroundthe circular raceways u, by which movements ofthe Aspools each strand is caused to pass around two other strands, thus forming a cord with an interlocking twist, the rotation of the table f elongated and pointed, one of these points projecting into a straight slot before the carrier leaves a circular slot, and into the next circular slot before the carrier leaves the straight slot, by which means the change in the direction ot' motionis effected as desired. I

The numbers of the teeth of the gears ofthe plates T U are so proportioned with respect to each other that the forks or bifurcations p r will be brought into their proper relative positions at the desired times.

A small portion, af, of the table G is made removable to allow of the insertion and removal of the spool-carriers W, this portion a being held in place by a screw, b.

A is the take-ott roll, which is rotated at the desired speed by a horizontal shat't, B', connected with the driving-shaft by suitable mechanism, which forms no part of my presf hollow, to allow ot' the passage through it of a piece of wire, cord, or other suitable material to Jform a core around which the strands may be entwined.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The spool-carrier plate G, provided with.

a series ofcircularraceways, u, arranged around a common center and connected by a series ot' straight short raceways, t, tangential to the circular raceways u, substantially as described.

2. lThe table G, having the raceways t u and platform H connected thereto, in combination with spool-carriers W, forked plates T and U, constructed as described, and the gears M N O P Q 1t S, for actuating the carriers W and causing them to travel in the raceways t u, substantially in the manner and for the purpose set forth.

Witness my hand this 2d day of June, A. D. 1875).
